Hi,

Unfortunately, at least for the time being, a purchasing possibility is not offered.

Re: Elmer capabilities in acoustics

Hi,

My impression is that these proprietary solvers will be made openly distributable in future, but I cannot guess when this will actually happen. I'm afraid that hoping it to happen in near future may be too optimistic.

Re: Elmer capabilities in acoustics

Hi, The linearized Navier-Stokes solver in the frequency domain is an outcome of contracted research. Unfortunately this solver is not openly available currently, so for performing time harmonic acoustic analyses the open source version of Elmer does not offer anything else than the Helmholtz solver...

Re: Navier-Stokes equations

Hi, It is not easy to say what is the best way of formulating the NS system. Here are however some possibly noteworthy points: - If the intention is to prescribe the true surface force on a part of the boundary, the default formulation for handling the diffusive term is the only consistent choice. I...

Re: Navier-Stokes equations

Hi, These options relate to how the weak formulations of the viscous and the pressure gradient terms are written. In the case of "DivDiscretization" the viscous term is integrated by parts by using the equation -(2 div D(u),v) = (grad u, grad v) + (div u, div v) + boundary terms. Otherwise one uses ...
